Federal
Conical Canister
This non-excavated specimen is an example of the classic-style canister
that both the Federal and Confederate forces used in the 12-pounder (4.62-inch caliber)
smoothbore cannon. The tin cylinder was dipped into a lacquer of beeswax dissolved
in spirits of turpentine to prevent it from rusting. Canister was designed to be
fired at close range with a resulting devastating effect on the enemy. It contained
rows of iron balls packed with dry, sifted sawdust. Go
